I dette indlæg vil jeg dele med dig en komplet Laravel 8 blød sletning og gendannelse af slettede poster tutorial. Når vi udvikler CRUD-operationer i Laravel, er vi nogle gange nødt til at implementere bløde sletninger. Så hvis vi forkert slettede den specifikke post, kan vi nemt gendanne dem. Derfor er dette vigtigt og skal eksistere i vores Laravel-applikation.

I denne artikel lærer du et komplet redskab med Laravel soft delete og hvordan du gendanner de slettede poster med eksempel.

Trin 1:Laravel-installation

Hvis du ikke har en Laravel 8-installation i dit lokale, skal du bare køre følgende kommando nedenfor:

composer create-project --prefer-dist laravel/laravel laravel-soft-delete

Når det er gjort ovenfor, skal vi installere Laravel Collective Package, kør følgende kommando nedenfor:

composer require laravelcollective/html

Trin 2:Databasekonfiguration

Hvis dit Laravel-projekt er frisk, skal du opdatere dine databaselegitimationsoplysninger. Bare åbn .env-filen i dit Laravel 8-projekt.

.env

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=your_database_name_here
DB_USERNAME=your_database_username_here
DB_PASSWORD=your_database_password_here

Trin 3:Opsætning af migrering

Lad os oprette en migrering for vores **laravel blød sletning **eksempelprojekt. I dette eksempel bruger vi brugerens tabel, hvor migreringen allerede eksisterer i Laravel-installationen. Så vi skal bare redigere den migration. Se opdateringskoden nedenfor:

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateUsersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->id();
            $table->string('name')->nullable();
            $table->string('email')->unique();
            $table->string('username')->unique();
            $table->timestamp('email_verified_at')->nullable();
            $table->string('password');
            $table->softDeletes();
            $table->rememberToken();
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('users');
    }
}

Som du kan se, tilføjede vi $table->softDeletes(); metode til at implementere Laravel soft delete.

Lad os nu køre følgende kommando nedenfor:

php artisan migrate

Trin 4:Opsætning af ruter

I mit eksempel vil jeg manuelt oprette mine crud-ruter. Bare åbn "routes/web.php" fil og tilføj følgende ruter.

<?php

use Illuminate\Support\Facades\Route;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::group(['namespace' => 'App\Http\Controllers'], function()
{   
    /**
     * Home Routes
     */
    Route::get('/', 'HomeController@index')->name('home.index');

    Route::group(['prefix' => 'users'], function() {
        Route::get('/', 'UsersController@index')->name('users.index');
        Route::get('/create', 'UsersController@create')->name('users.create');
        Route::post('/create', 'UsersController@store')->name('users.store');
        Route::get('/{user}/show', 'UsersController@show')->name('users.show');
        Route::get('/{user}/edit', 'UsersController@edit')->name('users.edit');
        Route::patch('/{user}/update', 'UsersController@update')->name('users.update');
        Route::delete('/{user}/delete', 'UsersController@destroy')->name('users.destroy');
        Route::post('/{user}/restore', 'UsersController@restore')->name('users.restore');
        Route::delete('/{user}/force-delete', 'UsersController@forceDelete')->name('users.force-delete');
        Route::post('/restore-all', 'UsersController@restoreAll')->name('users.restore-all');
    });
});

Som du kan se, tilføjede vi gendannelse, tvungen sletning og gendan-alle ruter. Du vil se vores controller-kode for disse ruter.

Trin 5:Opsætning af model for vores bløde sletning

Som du kan se nedenfor importerede vi brugen Illuminate\Database\Eloquent\SoftDeletes; klasse og bruge den i vores brugermodel.

<?php

namespace App\Models;

use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Sanctum\HasApiTokens;
use Illuminate\Database\Eloquent\SoftDeletes;


class User extends Authenticatable
{
    use HasApiTokens, HasFactory, Notifiable, SoftDeletes;

    /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'users';

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name',
        'email',
        'username',
        'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password',
        'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    /**
     * The attributes that should be mutated to dates.
     *
     * @var array
     */
    protected $dates = ['deleted_at'];

    /**
     * Always encrypt password when it is updated.
     *
     * @param $value
     * @return string
     */
    public function setPasswordAttribute($value)
    {
        $this->attributes['password'] = bcrypt($value);
    }
}

Trin 6:Laravel Soft Slet &Gendan slettede Records Controller-metoder

Indeksmetode inde i UserController.php, som du kan se, har jeg tjekket om der er en status med den arkiverede værdi fra anmodningen og kalder metoden $users->onlyTrashed() så kun soft deleted vil blive vist på listerne.

/**
 * Display all users
 * 
 * @return \Illuminate\Http\Response
 */
public function index(Request $request) 
{
    $users = User::latest();

    if($request->get('status') == 'archived') {
        $users = $users->onlyTrashed();
    }

    $users = $users->paginate(10);

    return view('users.index', compact('users'));
}

I denne metode inde i UserController.php kaldte jeg withTrashed() og gendan() metoder dette vil give os mulighed for at gendanne den slettede post.

/**
 *  Restore user data
 * 
 * @param User $user
 * 
 * @return \Illuminate\Http\Response
 */
public function restore($id) 
{
    User::where('id', $id)->withTrashed()->restore();

    return redirect()->route('users.index', ['status' => 'archived'])
        ->withSuccess(__('User restored successfully.'));
}

Dette er implementeringen af ​​tvunget til at slette posten i papirkurven ved hjælp af forceDelete() metode.

/**
 * Force delete user data
 * 
 * @param User $user
 * 
 * @return \Illuminate\Http\Response
 */
public function forceDelete($id) 
{
    User::where('id', $id)->withTrashed()->forceDelete();

    return redirect()->route('users.index', ['status' => 'archived'])
        ->withSuccess(__('User force deleted successfully.'));
}

I denne handling kaldte vi onlyTrashed() og gendan() metoder, så vi alle vil gendanne de optegnelser, der er smadret.

/**
 * Restore all archived users
 * 
 * @param User $user
 * 
 * @return \Illuminate\Http\Response
 */
public function restoreAll() 
{
    User::onlyTrashed()->restore();

    return redirect()->route('users.index')->withSuccess(__('All users restored successfully.'));
}

Trin 7:Laravel Soft Delete User Controller

Nedenfor er den komplette kode til vores UserController.php med implementeringer af Laravel 8 blød sletning og gendannelse af slettede poster.

<?php

namespace App\Http\Controllers;

use App\Models\User;
use Illuminate\Http\Request;
use App\Http\Requests\StoreUserRequest;
use App\Http\Requests\UpdateUserRequest;

class UsersController extends Controller
{
    /**
     * Display all users
     * 
     * @return \Illuminate\Http\Response
     */
    public function index(Request $request) 
    {
        $users = User::latest();

        if($request->get('status') == 'archived') {
            $users = $users->onlyTrashed();
        }

        $users = $users->paginate(10);

        return view('users.index', compact('users'));
    }

    /**
     * Show form for creating user
     * 
     * @return \Illuminate\Http\Response
     */
    public function create() 
    {
        return view('users.create');
    }

    /**
     * Store a newly created user
     * 
     * @param User $user
     * @param StoreUserRequest $request
     * 
     * @return \Illuminate\Http\Response
     */
    public function store(User $user, StoreUserRequest $request) 
    {
        //For demo purposes only. When creating user or inviting a user
        // you should create a generated random password and email it to the user
        $user->create(array_merge($request->validated(), [
            'password' => 'test' 
        ]));

        return redirect()->route('users.index')
            ->withSuccess(__('User created successfully.'));
    }

    /**
     * Show user data
     * 
     * @param User $user
     * 
     * @return \Illuminate\Http\Response
     */
    public function show(User $user) 
    {
        return view('users.show', [
            'user' => $user
        ]);
    }

    /**
     * Edit user data
     * 
     * @param User $user
     * 
     * @return \Illuminate\Http\Response
     */
    public function edit(User $user) 
    {
        return view('users.edit', [
            'user' => $user
        ]);
    }

    /**
     * Update user data
     * 
     * @param User $user
     * @param UpdateUserRequest $request
     * 
     * @return \Illuminate\Http\Response
     */
    public function update(User $user, UpdateUserRequest $request) 
    {
        $user->update($request->validated());

        return redirect()->route('users.index')
            ->withSuccess(__('User updated successfully.'));
    }

    /**
     * Delete user data
     * 
     * @param User $user
     * 
     * @return \Illuminate\Http\Response
     */
    public function destroy(User $user) 
    {
        $user->delete();

        return redirect()->route('users.index')
            ->withSuccess(__('User deleted successfully.'));
    }

    /**
     *  Restore user data
     * 
     * @param User $user
     * 
     * @return \Illuminate\Http\Response
     */
    public function restore($id) 
    {
        User::where('id', $id)->withTrashed()->restore();

        return redirect()->route('users.index', ['status' => 'archived'])
            ->withSuccess(__('User restored successfully.'));
    }

    /**
     * Force delete user data
     * 
     * @param User $user
     * 
     * @return \Illuminate\Http\Response
     */
    public function forceDelete($id) 
    {
        User::where('id', $id)->withTrashed()->forceDelete();

        return redirect()->route('users.index', ['status' => 'archived'])
            ->withSuccess(__('User force deleted successfully.'));
    }

    /**
     * Restore all archived users
     * 
     * @param User $user
     * 
     * @return \Illuminate\Http\Response
     */
    public function restoreAll() 
    {
        User::onlyTrashed()->restore();

        return redirect()->route('users.index')->withSuccess(__('All users restored successfully.'));
    }
}

Trin 8:Indeksbladsvisning
